Drop dependency on LayoutObject in fetch/

Drop dependency on LayoutObject in fetch/

Move out code from ImageResource depending on LayoutObject. Instead
request pre-caching explictly at the three places that currently has
reason for doing so.

The pre-caching itself is moved to BitmapImage and made part of
Image::currentFrameKnownToBeOpaque as a special metadata mode.
